VEHICLE WHEEL.

APPLICATION FILED sEPT.27. 191s.

Patented Mar. 28, 1916.

' mama .To all whom it may comic r12 -Be it known that I, Tnoms E.MnmiA'Y,

ila citizen of the United States, residing at New'Y'ork, in the countypfNew York and State of NewYork, have invented acertain new and usefulImprovement in Vehicle- YVheels, 'of which the following is aspecification. 1

The invention relates tovehicle .wheels of metal, and more especially toa demountable rim therefor.

The invention has for its obj ect to simplify I the construction, tofacilitate the removal 7 and substitution of the rim, and to enable saidrim to be both clamped and tightened in place on the fixed rim, by oneand the an inclined portion of said flange, flhe,

of each member is headed, ex-

- :tends through and has tubular spo a t0 same operation.

A flxed rim, preferably homogeneously united to the metal spokes attheir butt ends, has an outwardly turned edge on'one side to receive theusual tire-holdingrim, and.

at the other side'is inwardly flanged, the flange bearing against thespokes, and, if desired, being weldedto them.- A number of wedge-shapedclamping members are pivoted to the flange, preferably'at points be---tween the spokes. Each member at one end has a concave. projection whichengages the side of the movable rim opposite to that received in theconcavity of,the fixed rim, and at'its other end is beveled to coactwith pivot bolt flange and member, andis' prorided with a nut. en thenut is-set -np, 'the member acts asa. wedge cooperating with both flangeand rim, rim outwardly to tighten the same,

and forcing the while also at the -same time clamping the movable rimupon theflxed'rim. When it is desired to remoteJjjthe rim, the nuts areloosened suflicientl *to permit the several members to be rotated ontheir pivots out of engagement with the rim, when said rim may be easilyslid 0d of the qfixedrim.

is a face elevation of a portion of the wheel; Fig. 2 is a section onthe line :12, a? of Fig. 1. Similar numbers of reference indicate likeparts; T i The body portion of the wheel is In the accompanyingdrawings, Figure 1' of metal, ends of which the fixed rim 2 ispreferably homogeneously united by electric welding. One

edge 3, of the fixed rim is turned outward.

0n the opposite side is a flange t which specification of Letterslatent.

bears against the welde'd thereto. The inner edge,5; of the flan e islnclined outwardly at an obtuse j spokes, and white may bef ang e withrespectto the remainder of said r1m.', "Substantially "wedge-shaped(:lamping members 8 are pivoted to the flange 4, pr eferably at pointsbetween and equidlstant' from the spokes, by means of, headed-bolts 9which pass through said flange and said members, and are'threaded to'receive -nuts 10. The inner endoteach member 8 is beggeled to bearagainstthe inclined portion 5.

5f the surface of flange 4. A ril-ejection 11 on the outer endofeach-member '8 is made concave to bear against the convex side of themovable rim 6. Each member 8 therefore, substantially a wedge-one Jtaceof which is the beveled end eoiiperating with the portion 5 ofifixed rimflange. 4, and the other face oji which isthe concavity of pro ection 11coiiperating with the rim 6.

Hence hen the nut 10 isset-up, the menu J her is forcedbetween movablerim and fixed.

rim flange, and so cofiperating withboth,

acts to tighten the movable rim. All the; r same time the movable rimbecomes clamped between the outwardly turned edge 3 of the fixed rim and';'the projections 1120f the several clamping members'S,

en it is desired to dismount the rim 6, the nut 10 is loosened and movedoutwardly on its bolt,,-'thus permitting the members 8 to be moved inthesame direction and so withdrawn from contact with rim and flangesuficiently to enable them tobe rotated onsaid boltsto bring theirprojections 11 out of engagement with the rim. 0d of the fixed rim, and,if desired, another shoe-carrying rim may be substituted, the

members 8 then being turned back into en- :1 gaging position and thenuts set up as betore'to clamp and tightenthe rim by a single operationof said members 1 I claim:

IL A vehicle wheel, comprising a single f fixed rim having one edgeoutwardly turned, a movable rim seated in the concavity at said fixedrim, an inwardly turned flange on-thdopposite edge of said fixed-[rammed-names, WW6, Application filed se tember 27,1915Q seiiainesaaew;

The rim 6. m then be an laterally Mill rim, the outer face of saidflange. forming v t1on to cooperate with with said movable rim anannular seat of substantially frusto-wedge shaped cross section, aplurality of clamping members of corresponding cross section, and meansfor moving said members into said seat to clamp said movable rim on saidfixed rim.

2. A vehicle Wheel, comprising a single fixed rim having one edgeoutwardly turned. an inwardly turned flange on the opposite side of saidfixed rim having a portion of its surface inclined at an obtuse angle tothe remaining able rim seated on said fixed rim, a plurality of movableclamping members mounted on said flange, each of said members having aflat middle portion and at one end thereof a concave projectionreceiving said rim and having at its opposite end an inclined portheinclined surface of said flange. and means for moving said members toclamp said rim between said projections and said fixed rim.

3. A vehicle wheel. comprising a single fixed rim having one edgeoutwardly curved,

portion, a d'emountan inwardly turned flange on the opposite edge, theouter face of said flange having a flat portion and a portion inclinedat an obtuse angle to said flat portion, a plurality of clampingmembers, each having at its outer end a projection provided with aconcavity corresponding in shape to the curved portion of said rim, aflat portion corresponding to the flat portion of said flange, and aninclined portion corresponding to the inclined portion of said flange,headed bolts extending through said flat portion of said flange and saidclamping members and threaded at their outer portions to receive nuts,and a removable rim seated in the concavity of said fixed rim andengaged on opposite edges by said curved portion of said fixed rim andsaid clamping members.

In testimony whereof have aflixed my signature in presence of twowitnesses.
